cago, in the county of Cool; and State ol' lllinois, have invented new and useful Improvev designed `'to emit direct raysin every 'dire f' tion, and whereby increased brillianoy ie ohtained, the burner being adapted for use with ordinary illuminating' gas or a vapor mixturey produced from liquid l1ydro-carbonv A further object ofthe inyention is tin.l pro vision of a burner having aJ pluralityr ol tu.

wardly and downwardly extending' gas fon ducting passages at the end of each ol which 1s a mantle for receiving' therelrtnn.

Another obj ect is to provide a burner body of the character referred to adapted for. use in connection with a generator so arranged as to be heated by the hot gases from certain of the mantles, thereby adapting the lamp tor burning a liquid hydro-carbon.

With these objects in View and others, as will appear as the description proceeds, the invention comprises'thevarious novel features of coustruetion Eind arrangement ol parte which. will be more fully described here inafter and set forth with partit-.ularity in the claims nppended hereto.

In each extension is u soei;ete l. support 1U for the reception oi: the lower end o" aA inuntle4 Supporting' rod 1], whereby an u pright niwn-1^ tle i2 can he held over the hollow extension with the lower end oli' the mantle surrouinlingi` the latter, as shown in.

which is united with the inixor i there being.;

over the vaporizer 4l and the latter extends through an o ening inthe web 21 formed between the egs, there being a set screw 22 for holding the burner body in ixed position.

By adjusting the burner body back and forth, the section 19 moves therewith so that the opening 17 can be reduced or enlarged to vary the amount of air drawn into the mixer. The heat' rising from the bottom Set of mantles 7 serves to maintain the vaporizer vBat a suitable tem erature to effectively vaporiZe the liquid liydro-carbon' supplied tothe vaporizer. In order to insure against the passage of particles or sediment to the urner, a screen 23 is arranged at the discharge end of the va orizer and a screen 24 at the inlet of the va ve D.

In the form shown in Fig. 3, the generator B is arranged vertically between the mantles on the legs 2 and the u per or discharge end connected with the hol ow extension 5 of the burner body, and the air for producing the combustible mixture is supplied through a plurality of radial pipes 25 connected to and communicating with the hollow of the extension 5 so as to thereby supply air to mix with the vapor, the location of the pipes 25 being such that the air becomes more or less heated before commingling with the vapor.

From the foregoing description tallen in connection with the accompanying drawing, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the a'rt to whichI the invention appertains, and while I have ldescribed the principle of operation of the invention,

Vtogether with the apparatus which I now consider to be the best embodiment thereof, I desire to have it understood that the ap aratus shown is merely illustrative and t at such changes may be made when desired, as are within the scope of the claims.

Having thus described the invention, what I claim is:-

1. A burner comprising a body having upwardly and downwardly extending passages,

a screen threaded in the discharge end of the downwardly-extending assage, a bead on the lower end of the boni) a mantle secured to the body by the bead, a support rising from the body, a mantle on the said su pport,l a vaporizer on which the body is mounted for longitudinal movement, and a mixing device connected with the vaporizer and body and arranged to prevent the latter from turning on the vaporizer.

2. The combination of a burner body having upwardly and downwardly discharging passages and a common inlet communicating with the inner ends of the passages, upri ht and pendent mantles secured over the ischarge ends of the respective passages, screens set into the passages, a tube secured f to the body and communicating with the nected tubes for holding the body from turn! ing on the va orizer, and a valve connected to the end of t 1e vaporizer opposite from the return. v

In testimony whereof, I affix my signature in presence of two witnesses.
